PUZZLE.

SPECIFICATION formingpart of Letters Patent No. 767,645, dated August 16, 1904.

Application fiicf. July 9, 1903. Serial No- 164,857. "No model.

"o (117 whom it 11m 1 concern.-

Be it known that I, \ViLLIAu J. KELLY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful improvements in Puzzles, of which the following is a specification.

My invention relates to new and useful improvements in puzzles; and its object is to provide a simple and inexpensive device adapted to aiford considerable entertainment and amusement in the assembling or the detaching of its parts.

The invention consists in providing aset of strips which are adapted to.intcrlock when assembled in the proper manner and after being fastened together require considerable ingenuity in detaching the parts.

The invention consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and

illustrated in the accompanying drawings,

showing the preferred form of my invention, and in which Figure 1 is a perspective view showing the parts of the puzzle assembled. Fig. 2 is a similar view showing the position of two of the parts in dotted lines, and Figs. 3, 4, 5, 6, 7, and 8 are side views of the respective parts of the puzzle.

Referring to the figures by numerals of reference, 1 is a substantially rectangular strip of suitable material having a recess 2 in one edge which is equal in length to the width of two strips 3, which are similar to each other and each of which is provided in one face with a transvcrsely-extending groove 4. side of each groove and at the same distances therefrom are rectangular recesses 5, which are formed in one edge of the strip 3 and are equal in length to the width of the centers of strips 6. inch of these strips has a recess 7 formed in one edge for the reception of the central portion of the strip 1, and the bottom of the recess T is also recessed at the center, as shown at 8, for the reception of those portions of the strips 3 which are located be tween recesses 5 and grooves 4. A hey 9 forms the last member of the puzzle. This At eachkey is slightly tapered from one end to the other and is approximately the same size as the strips 1, 3, and 6.

In assembling the puzzle the strips 6 are placed with their recessed edges together, and strip 1 is then inserted therehetween so as as to rest within one end of the aperture formed by the two recesses. It will be understood that the bottonrof the recess 2 will register with the adjoining ends of the recesses 8 in view of the fact that the distance from the one end of recess 7 to the adjacent end of recess 8 is equal to the width of the central portion of strip 1. The strips 3 are then placed within the recess '3 at opposite sides of strip 6, and the recesses 5 of said strip 3 rcccive the central portions of strips 6, while the registering grooved portions of the strips 3 extend into the aperture formed by recesses 7 and 8, the walls of said groove alining with the inner facesof the recesses T. In order to permit the strips 3 to be readily inserted into the recesses 2 and s, l preferably bevel one edge of the inner face of each recess 5, so as to permit said strips 3 to be inclined while being placed in position. I have shown these bevels at 10 in Figs. 2, 7, and 8. After the parts have been assembled as above described the key 9 is inserted into grooves t and through those portions of the recess 7 which are open. This key will securely bind the parts together, as illustrated in Fig. i. In order to detach the parts of the device, it is necessary to iirst discover the key 9 and then remove the same. The strips 3 can then be tilted upward out of the recess 2, and the other parts will, as is obvious, become Slhil' rated. As all of the strips when assembled are similar in appearance, it is obvious that extreme diiiiculty will be experienced in locating the key 9.

in the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as i am aware that modifications may be made therein without departing from the spirit or sacriiicing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus deserihed the invention, what is claimed as new is A puzzle formed of a plurality of strips, one of which has a rectangular groove in one edge, two of said strips each havimg a reetai'ignlar groove in one edge provided with a centrally disposed rectangular recess in its inner wall equal in width to the thickness of the strip, two of said strips each having a centrally-l0- eated lransversely-extending groove in one face equal in width to the thickness of the strip and rectangular recesses in one edge at opposite sides of said groove and provided with heveled inner edges said reeesses heing equal in width to the thiekness ol' the slrip and a Wedge-shaped strip. said strips lveing' adapted to lit within the grooves and reeesses and interlock to form a ('hinese rross, said strips being locked in position h v the wedgeshaped strip.

In testimony whereof I allix my signature in presence of two witnesses.
